We’ve come close to doubling battery capacity per volume in that time.

The battery was the single largest module by a long shot in an iPhone 6, and now you can get the same capacity in a much smaller volume. We’ve also lost other bulky items like the home button and headphone jack.

The camera on the current gen has its own expanded volume area of the case, so I don’t buy that they couldn’t just use the same hump they use on literally all of their phones. Sure Face ID is new, but I’ve seen the size of that module, and it is only slightly larger than the selfie camera from back then that it replaced.
